FFICEQ PATENT GILBERT \V. BRADLEY, OF SUNDERI'JAND, VERMONT. I

BUTTER-PACKAGE.

SFECIFICATION forming part of Letters Patent No. 355,252, dated December 28, 1886.

Application filed April 5,1886. Serial No. 197,812. (No model.)

To aZZ whom, it may concern:

Be it known that I, GILBERT W. BRADLEY, of the town of Sunderland, in the county of Bennington and State of Vermont, have invented certain Improvements in Butter-Pack ages, of which the following description, in connection with the accompanying single sheet of drawings, constitutes a specification.

This invention relates to improvements in the construction of boxes or receptacles for packing butter and analogous substances, which are made from thin veneer or scale board, in which the j oints and angles are confined and stiffened by means of metallic bands.

The drawings exhibit fully my invention.

Figure l is a perspective view of one of my butter-packages with the cover removed. Fig. 2 is a view of the cover thereof. Fig. 3 is a plan view of one of the blanks for-a corner band before it is bent for use; and Fig. 4 is a sectional perspective view of the angle or corner bend of a bottom band, showing the style of the bent crease or groove wherein the wood piece constituting the bottom of the box finds lodgment and is confined. Fig. 5 shows a method of forming the joint between the ends of the body-strip by uniting the ends at the corner of the box. Fig. 6 shows how a joint so formed is fastened by a rivet passed through one of the folded-over tongues.

Boxes and packages have heretofore been made from thin material, like veneer, strawboard, 810., by transversely scoring a rectangular strip of such material at the points where the corners of the box are to occur, and then breaking or bending the strip around into the desired form of a polygonal box and providing such bent structurewith abottom, and securing sides and bottom each to the other with bands or other appropriate means. In the case of pasteboard boxes so made, the scored corners would be necessarily weak by reason of the material being partially cut through, and such weakness has been overcome by pasting or gluing a piece of paper around the corner, so as to compensate for the fracture and at the same time stiffen the walls of the box. By my improvements I accomplish similar results by other means and in another way,as hereinafter stated.

- I construct:my packages by scoring a thin box and have'the ends overlap, to admit of their being sewed or otherwise united, (at the points where the corner bends are to occur,)

and then bending or breaking such stripsaround into the desired polygonal shape to constitute the walls of the package. I then re-enforce each corner of the box where the scoring occurs by applying thereto a metallic stiffening-piece, C, bent to fit the angle of such corner from a metal blank of the form seen in Fig. 3, and bending the tongues e e e 6 over the edges of the veneer A into the shape shown at b b, Fig. 1. Herein consists the leading feature of my improvement, as these metallic corner-stiffenings G O Q C so applied require no rivets, glue, or other appliance or means for their application or confinement, and when attached prevent the walls from splitting, or, if by accident one gets split, they prevent the broken sections from getting separated or thrown out of place. I unite the overlapped ends of the veneer as shown, and secure the lap preferably by stitching, as shown at S.

Box and cover are similarly made as to holding the piece which constitutes either the top or bottom. The means for this purpose consist of a tin or metallic band having a flanged edge, 9 9, turned at right angles with the main web by a tool which leaves the crease c c, Fig. 4, for the reception of the edge of the strip of wood which is to constitute the top B or bottom of the box, as the case may be. This band D is bent into the requisite polygonal form to just slip onto or receive the hoop or walls A A of the box. assembled. by springing a bottom blank into the creased band D, and then pressingthe body A A into said band, so as to bring the parts together, as shown in Fig. 1. This done, the band is fastened to the walls of the box by rivets or analogous fastenings, as seen at f, Fig. 1. The cover is made by simply springing one of the cover-blanks B into a creased band, D, as shown in Fig. 2.

The parts of the rivets and ends of the corner-stiffenings G G C G which are exposed inside to the contents of the box are prevented from contaminating the contents of the box when filled with butter, &c., by a coat of odor- The parts are then less paraffine-wa-x, with which the interior of the box is coated.

Another feature of my invention is specifically shown in Figs. and 6. These figures show how the union or joint of the two ends of the wall or body-piece may be made to fall under the stififeningstrip at one corner of the box. In this case I score the body-piece transversely a short distance from the end thereof, so as to leave a short lapping flap, A, which is bent around at a right angle to the side A. The opposite end of the wall-strip A is brought j around so that its end comes in undefthe cornerstiffener just even with the scoring of the opposite end A. The lip e is then bent or folded over, as well as its companion lip, as in Fig. 6. This done, the lip e is' fastened to the wood of the box by means of a rivet,'r, which holds all together firmly, so that the side A cannot be easily withdrawn from the gripping inelosure of folded lip 6. By this method of making the corner the seam is concealed and the box has the appeafanee of being constructed without any seam.

I therefore claim as my invention 1. Abox-body of scored and bent material having each corner re-enforoed by a metallic strip longitudinally bent to fit the angle of a prismatic box and provided with tongues at each end thereof, which are bent over the top and bottom edges, and then against the inside of the material of the wall of the box, in the manner shown and described, and for the purposes set forth.

2. Abutter-package consisting of the transversely-seored body-piece A, metallic cornerbent over the top and bottom edges of the bod y-piece, applied and fastened as shown and described, one or both of the top tongues of the angle-strip which covers the angle of the box where the ends of the body-piece meet being positively fastened to the laps of the body-strip to prevent spreading of the corners,

as set forth.

In testimony whereof Ihave hereto subscribed my name, at North Bennington, Vermont, this 27th day of March, A. D. 1886.
